Hey Greg, I had seen your post before, but I did not test it. I'm
inspired by "telnet" method. I use cli lms. maybe there is a simple way
for doing this. right now I don't have pcp and raspberry pi until
tomorrow.
but I really like share my code with you.
Code:
--------------------
sudo echo "17" > /sys/class/gpio/export
sudo chown -R tc /sys/class/gpio/gpio17/
sudo echo "out" > /sys/class/gpio/gpio17/direction
mac=$(sudo cat /sys/class/net/wlan0/address)
command=$mac' connected ?'
host='192.168.1.17 9090'
#///////////////////////////
program(){
result=$(
(
echo "$command"
sleep 1
echo "exit"
) | timeout -t 5 telnet $host )
if [ "$result" != "Terminated" ]
then
data=$( (echo "$result") | cut -d ' ' -f3)
if [ $data -eq 1 ]
then
return 1
else
return 0
fi
else
return 0
fi
} #end of program
#////////////////////////////////
while true;
do
program
dd=$?
if [ $dd -eq 1 ]
then
echo "Connected"
sudo echo "1" > /sys/class/gpio/gpio17/value
else
echo "Not Connected"
sudo echo "0" > /sys/class/gpio/gpio17/value
fi
sleep 2s
done
--------------------
yeah, "$(pcp_lmsip)" this is exactly what I want .instead of writing
this code I could just check "$(pcp_lmsip)" this variable.:p if it is
filled turn on led.
I don't know if possible 20 30 pcp telnet to one lms server at one time
and lms windows app can handle their requests every 5 sec to check their
connection, it works or not. but just checking "$(pcp_lmsip)" , is not
dependable to network and telnet.
